摘要
建筑体形系数是体现建筑形态的重要指标,以上海地区的气候条件作为夏热冬冷地区的典型代表,采用动态能耗模拟软件De ST-c对办公类建筑进行能耗计算,引用被动容积率的概念,考虑建筑利用自然通风及日光照明的最大潜力,研究建筑体形系数与建筑能耗之间的关系。研究表明,夏热冬冷地区办公建筑体形系数越大,建筑的被动容积率越大,利用自然能源的潜力越大,建筑能耗越低,该结果为被动式建筑设计提供参考。
Building shape coefficient is an important index in building energy efficiency design. This study is based on the concept of passive volume and assumed to fully use of passive energy, natural ventilation and daylighting, in the passive zones of a building. Taking a group of office buildings in Shanghai as an example,with the help of the dynamic simulation software DeST-c, the relationship between the building shape coefficient and building energy consumption is studied. It shows that in hot-summer-and-cold-winter area of China, the bigger shape coefficient, the bigger passive volume ratio, the more potential to use passive energy, the less building total energy demand. It provides a reference for passive building design.
